M(x, y) = ((x1 + x2)/2, (y1 + y2)/2) = ((-2 + 6)/2, (5 - 9)/2) = (4/2, -4/2) = (2, -2)

kirza4 [7]

Answer:

Stratified sampling

Step-by-step explanation:

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

In this question:

Population divided into groups, and random samples are drawn from the groups. This is a mark of stratified sampling.

Steve can jog 14 miles in 2 hours. At this rate, how many miles can he jog in 1/4 hour?

Assoli18 [71]

Answer:

1 3/4 miles in 1/4 hour.

Step-by-step explanation:

Write and solve an equation of ratios:

x (1/4) hr

--------- = ------------

14 mi 2 hr

Cross multiplying, we get 2x = (1/4)(14), or

x = (1/4)(7), or x = 7/4

Steve can jog 7/4 miles in 1/4 hour. That's 1 3/4 miles in 1/4 hour.

Find the volume of the composite solid. Round your answer to the nearest tenth.

amm1812

Answer:

Volume of the Figure $=825.38m^3$

Step-by-step explanation:

Volume of the figure = Volume of the Upper cone+Volume of the lower cone

Volume of a cone = $\pi *r^2*\frac{h}{3}$

Volume of the Upper Cone with

$height=12m$

$radius=6m$

$3.14*6*6*\frac{12}{3}$

$=3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3$

Volume of the Lower cone with $radius=6m$ and $height=18m$

$=3.14*6*6*\frac{18}{3} \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3$

Volume of the Whole Figure = $147.14+678.24$

Volume of the Figure $=825.38m^3$
